Staying Safe in the Science Lab: How to Follow Essential Safety Practices
Introduction: Would You Board a Plane Without Safety Rules?
Imagine boarding a plane where the crew skipped the safety checks. No seatbelt instructions, no emergency plan, no communication. It would feel reckless — maybe even dangerous.
A science lab without safety practices is no different.
Just like pilots follow strict protocols to fly safely, middle school and high school students and teachers need a set of rules to conduct science experiments responsibly. Whether it’s mixing chemicals, handling glassware, or working with open flames, lab safety is essential to prevent accidents, ensure learning, and build confidence.
In this article, we’ll walk through key lab safety practices, explore an interactive classroom activity, and use JoVE’s visual tools to reinforce smart science habits.
Why Lab Safety Is More Than Just Rules
Teaching science lab safety practices isn’t just about ticking boxes. It’s about creating a culture of responsibility. Students who understand why safety rules matter are more likely to follow them — and more empowered to think critically during experiments.
Key goals of lab safety instruction:
- Prevent injuries or accidents
- Encourage awareness of surroundings
- Teach responsibility when using lab tools
- Build respect for scientific materials and procedures

Essential Lab Safety Rules for Students
Make sure students understand these basics before any hands-on activity:
- Always wear safety goggles, gloves, and protective clothing when required.
- Never eat, drink, or chew gum in the lab.
- Read instructions carefully before starting any experiment.
- Handle all equipment, especially heat sources and glassware, with care.
- Immediately report any spills, injuries, or broken materials to the teacher.
- Know the location of emergency exits, fire extinguishers, and eyewash stations.
- Dispose of chemicals and biological materials safely, as instructed.
Use visual aids, safety posters, and JoVE Science videos to make each rule stick.
Classroom Activity: Lab Safety Role-Play Challenge
Turn lab safety into a game students won’t forget.
Setup:
Create 5-6 lab safety “stations” around the room — each with a mini-scenario (correct and incorrect behavior). Examples:
- A student wearing open-toed shoes
- Unlabeled chemical containers
- A student using equipment without reading instructions
Instructions:
- Divide the class into small groups.
- Assign each group to a station.
- Ask them to identify what’s wrong and how to fix it.
- Rotate stations and repeat.
- End with a class debrief using JoVE’s safety video for reinforcement.
This activity gets students up, thinking, and applying safety rules in real contexts.
Common Lab Safety Mistakes (and How to Avoid Them)
❌ Forgetting PPE (gloves, goggles) → ✅ Build habits through repetition
❌ Rushing through procedures → ✅ Encourage thoughtful reading
❌ Mislabeling chemicals → ✅ Reinforce clear labeling in all activities
❌ Ignoring small spills → ✅ Emphasize the importance of immediate reporting
🎥 Use JoVE’s Visual Demonstrations to reinforce correct procedures and model what safe behavior looks like in real labs.
Why Safety Training Builds Better Scientists
Students who practice lab safety learn more than just rules. They develop:
- Attention to detail
- Respect for procedures
- Confidence working with scientific tools
- Habits that extend beyond the classroom
These are foundational skills that prepare students for high school science and beyond.
Conclusion: Make Safety a Core Part of Every Science Lesson
From goggles to gloves to great habits, science lab safety practices are a foundational part of quality science instruction — especially in middle and high school classrooms.
Use interactive scenarios and JoVE’s standards-aligned science videos to make these lessons stick.
